Area code 205 was assigned to the original numbering plan area for Alabama, created in 1947 when the NANP was placed in operation by AT&T. It encompassed the entire state. By the 1990s, the state's growth and the proliferation of cell phones and pagers threatened exhaustion of the numbering pool. In 1995, the area was divided and area code 334 was created in relief to serve the area from Montgomery southward. The numbering plan area was reduced in size in 1998, when the northern and eastern portions were assigned area code 256.[1]

In October 2019, numbering plan area 205 was converted to an overlay plan, adding area code 659 to the same region. This change mandated ten-digit dialing for all calls.[2][3]
